i recently helped my dad put a different motor in his old 75' 750 that he bought brand new in 75'....the motor was stuck so we put a different 750 motor in it..every cover on the engine is chrome so it looks pretty sweet. now it could use a new paint job and new tires and is road ready...i guess he is planning on selling it, so is it worth putting the extra money in it for tires and paint? i mean it would look 100x's better but he doesnt wanna spend that money you know what i mean..? what im asking is what could he get for it right now, 75' cb750 with 30,000 miles...compared to it with probably $150 in new tires and idk im guessing kind of a pretty penny in paint....but what could it bring then..? thanks...
